Changes since v1: - Dropped RFT tag - Switched to generic (tx|rx)-internal-delay-ps - dwmac-sun55i driver bits - Changed dev_err() + return to dev_err_probe() - Added check of return value from syscon regmap write - Changed driver name to match file name - sram driver bits - Fixed check on return value - Expanded commit message - dtsi - Fixed typo in tx-queues-config - cubie a5e - Add PHY regulator delay - Link to v1: https://lore.kernel.org/all/20250701165756.258356-1-wens@kernel.org/ This series adds support for the second Ethernet controller found on the Allwinner A523 SoC family. This controller, dubbed GMAC200, is a DWMAC4 core with an integration layer around it. The integration layer is similar to older Allwinner generations, but with an extra memory bus gate and separate power domain. Patch 1 adds a new compatible string combo to the existing Allwinner EMAC binding. Patch 2 adds a new driver for this core and integration combo. Patch 3 extends the sunxi SRAM driver to allow access to the clock delay controls for the second Ethernet controller. Patch 4 registers the special regmap for the clock delay controls as a syscon. This allows the new network driver to use the syscon interface, instead of the following dance which the existing dwmac-sun8i driver does: of_parse_phandle(); of_find_device_by_node(); dev_get_regmap(); With this change in place we can also drop the above from the dwmac-sun8i driver. Patch 5 adds a device node and pinmux settings for the GMAC200. Patches 6 and 8 add missing Ethernet PHY reset settings for the already enabled controller. Patches 7, 9, and 10 enable the GMAC200 on three boards. I only have the Orangepi 4A, so I am asking for people to help test the two other boards. The RX/TX clock delay settings were taken from their respective BSPs, though those numbers don't always work, as is was the case for the Orangepi 4A. Please have a look and help test on the Avaota A1. I don't expect any issues there though, since the PHY is always on, unlike on the Cubie A5E. Patches 1 and 2 should go through net-next, and I will take all the other patches through the sunxi tree.
